It dectect automatically USB device but not install ITSELF the drivers. It need my intervention.

XP ultimate version is a full XP version (modified because of added features but not less features).

I think the drivers are not missing in this install because I no need any CD to install USB device, I just need to click "next" ("suivant" in french) in the dialog box which appears when I plug the device (see the joined picture - sorry it is in french but i hope you will reconize this dialog box). After that , Xp find itself the good drivers and instal them.

A device which is already installed will prompt for drivers again if its not inserted in exactly the same socket (and using hubs makes it worse) yet will then find the drivers on its own with no need for a CD or Web.

I haven't seen anyway round it but a snoop around the registry might reveal something
